QCan you walk through an example?
With Distance (km) 10, Time (min) 55, the answer is Pace 5.5min/km.
QWhat do I need to enter?
Enter Distance (km), Time (min). The result recalculates as you type, and an empty box counts as zero.
QHow much does the answer move if I change a number?
Changing only Distance (km) moves the answer to Distance (km) 5 → Pace (min/km) 11 and Distance (km) 20 → Pace (min/km) 2.75. The table below lays out five steps.
QHow are the numbers rounded?
Money is shown to the nearest whole unit, percentages to one decimal place and everything else to two. What you see is rounded; the calculation itself carries the unrounded value forward.
